I also read that Efke 25 film pushed two stops and developed in Ilford Microphen developer turns into a balck-and-white negative with almost no mid tome...

Hi Pete! I'm very sorry to hear about your condition, but it's impossible to say that exposing yourself to hydrochinon has anythig to do with it.
